Overview

Weltall Technology Corporation, founded in 2007 by a team of experienced engineers, is committed to delivering real-time, high-quality solutions grounded in our core values: Honesty, Justice, Diligence, and Passion.

Headquartered in Hsinchu, Taiwan, we operate service centers in Taichung, Tainan, and Kaohsiung to ensure localized support. In line with the global footprint of our key clients, we have established overseas subsidiaries in Phoenix, AZ (Welmade, USA), Kumamoto (Welsun, Japan), Singapore (Welstar).

Backed by a dedicated R&D, sales, and technical support team, we deliver advanced monitoring solutions, including:
• AMC (Airborne Molecular Contamination) monitoring systems for cleanrooms, ensuring optimal yield and environmental integrity
• VOC emission monitoring solutions (NMHC / THC / CH₄) for compliance and risk control
• ESG-related continuous gas monitoring systems supporting sustainability initiatives

We serve the semiconductor and electronics industries, as well as research institutes, providing not only gas analysis services but also customized system integration.

Weltall goes beyond distribution—we are a trusted total solution provider. Our comprehensive services cover analyzer selection, system design, data visualization software, on-site installation, pipeline construction, system validation, user training, and long-term maintenance. By integrating hardware, software, and services, we deliver tailor-made solutions that meet the evolving demands of high-tech manufacturing environments.

We are deeply grateful for the long-standing trust of our clients, which fuels our continued growth and innovation. At Weltall, we remain committed to advancing system integration technologies and delivering exceptional service to partners around the world.
